What Do I Do About the Guy I Lost My Virginity To

So I went on my spring break trip and ended up meeting a guy. Long story short - we had sex. He told my friends that he was really into me and we also hooked up the following night. But after that he began completely ignoring me. I'm happy because I would rather this happen with someone I didn't love but I'm sad because I feel completely rejected. What do I do to get over this?
